To all whom, if; 'ntrty/ concern:

Pittsburg, in the county of Allegheny and State of ful Apparatus for Mining, of which the following is afull, clear, ence being Pennsylvania, have invented new and useand exact description, referl had to the accompanying drawings. i Thls appl1cat1on is a division of my 'former I i application, iiled May 25, 1904, Serial No. 209,622, for a method of mining.-

rIhe object of my invention is to cheapen the 1 cost of producing ore from mineral veins in shaft-m1nes 1n districts to which the apparatus 1s applicable.

Before actual mining commences I sink a l working shaft, preferably to a great depthl say to two thousand feet, on which level all l subsequent work is conducted until after all the mineral values have been extracted from i ail the veins that lie above thatlevel, as stated below. l

When the work is conducted on the shafts have eut that cross-cuts all veins from one limit of i the property to the other. eral vein is reached and cross-cut by this main y tunnel a branch tunnel in the drift from the main tunnel and on the level of the latter is driven on the vein itself. :from the mineral vein is extracted from wall l/Vhenever a min- I Thereafter all ore i y overhead.

' to wall from the level of the main cross-cut tunnel upward continuously until the outcrop of the vein has been reached. As mining operations are thus conducted continuously upward in each separate drift, and preferably on each side of the main cross-cut tunnel, the floor is filled continuously around and over the outside of the arch of the drift-tunnel with a iilling of suitable material throughout the entire extent of such drift to the property limits as rapidly as the ore is extracted from the vein In this manner it is intended that the diifereuce between the level of the filling under foot and the level of the ore overhead shall be maintained at six, eight, or ten feet, as may be most convenient in removing the ore. In lieu of timbering I preferably use doublescrew jacks and timber blocks to temporarily support the ore rootl of the workings during mining operations, and these devices, while expensive in iirst cost, may be used continuously. 'Ihe ore from each drift is dumped from tram-cars as mined into the metallic chute or chutes 2, Figs. l and 8 to l2, which are preferably located every two hundred feet on the drift continuouslyr as the mining work progresses i'ipward, and such ore is continuously withdrawn from the hopper or hoppers at the bottom of such chute below by the Carman in the drift. The Carman takes an empty car, pushes it by hand to one of the hoppers 3 at and. iills it by gravity. He thereafter pushes it out onto the main line, after iirst placing in position the semaphore on the front of the car, which it contains ore or waste material, and the car is then transported to the ore-pockets at the foot of the ore-hoisting shafts, into which its contents are automat- Then the drift has been worked out and all of the mineral has thus been extracted from the vein completely toits top surface or outcrop or as close to the outcrop as the surrounding conditions render it safe to carry the mining operations, iilling material is then packed solidly from the end of such drift at the utmost limit of the property-line, and such back lilling is continued forward toward the main cross-cut tunnel. The tram-cars used in these underground workings are purposely made to unbolt, and each piece is of such size that itcan be lowered in the car that travels up and down in the manway. In similar manner after all of the ore has been drawn out of the last metallic chute the upper hopper is removed in sec- IOO lIO

tions, and the metallic chute is also unbolted l pins are driven linto place in corner-holes and lowered in sections, and the metal rungs l bored in the timbers at the mill.

on the manway-ladder are also then removed.

Fig'. l shows a drift-tunnel, with its car and the receptacle or alcove provided opposite the entrance to the upraise or manway for the storage-of the small car that operates in the manway and which is used to hoist and lower drills, explosives, timbers from which the upraise is constructed, and anything else that may be desired. The figure also shows the tubular metallic ore-chute with the gate at the bottom thereof for loading a car with ore by gravity. From the top level of the vitrified brickwork as the upraise is carried upward by reason of the extraction of the ores and the subsequent filling` twelve-inch timbers 5, cut to size at the mills, are used in the construction of the manway. These wooden pieces are simply set together, and wooden pins are driven through the corners. (This necessitates no timbermeu and no carpenterwork. They are comparatively small, and can be made at sawmills in the western country from scraps and from waste lumber, so that they can be procured at much lower prices than ordinary mine-timbers can be bought for.) As each square of the timbers is placed in position and as the filling-work progresses upward specially-prepared iron or steel rungs 6 are driven into holes provided in the timber for that purpose. Thus the workmen pass to and fro through the same passage-way that is used by the hoist-car. This car maybe hoisted and lowered by means of a hand-windlass. or preferably by a winch operated by compressed air. Where a serious deviation in the foot-wall occurs, as that shown in Fig. l, two timbers 7 are placed so as to span it and to prevent too great a deviation in the angle of the upraise.

Fig'. 2 illustrates the metallic ore-chute Q, air and water pipes, and the electric-lightwire and signal-wire conduits. lt also illustrates a manway 2 and the ladder 8, on which the workmen pass up and down. A carpasses up and down in the manway when it is in use. It also shows an ore-car in the drifttunnel standing under the spout of the metallic ore-chute in a suitable position for loading, the manner of setting the wooden timbers of which the manway and ore-chute spaces are made, and the ore-car track in the drifttunnel below.

Fig. 3 shows the upraise or manway with a car in position for loading under the spout of the ore-chute. It also illustrates the entrance to the manway and the tramway-track on which the car runs up into and down from the mine-workings through the manways.

Figs. a to 7 show the end pieces and side pieces of timber used in constructing the manways or upraises. These pieces are simply laid into their proper position on the upraise as the lling-work progresses, and wooden l l l l l l l l l Figs. 8 and 9 illustrate the sliding or telescopic adjustable ore-hopper 9 that is used at the top of the metallic ore-chute. They also illustrate an ore-car in position ready to dump ore into the chute while resting upon a section of the portable tramway. The metallic chute is preferably made in sections, and as mining-work and the filling' in the drift progresses steadily upward and the square timber sets are continuously added extensible provision must be made at the top end of the metallic ore-chute until the upraise reaches a point where a new section may be added. This is provided for by the telescopichopper, which is elevated from time to time as the filling progresses upward until a point has been reached where a new section of tubing may be added. The hopper is then again placed down in this new section. and it slides down telescopically thereon. The hopper is again elevated continuously upward, another section of tubing is added, and so the operation continues indefinitely. As each section of tubing is thus added provision is made in the upraise for securing it to the timbers and for holding it in its proper position. This is preferably accomplished by means of timber blocks or metal strips, as may be preferred. It will be understood that each section of tubing is only required to sust-ain its own weight and a part of the weight of the body of ore it A large proportion of the weight of the ore will be sustained by the gatepiece at the bottom, which is made of castiron and which rests on afoundation of vitrilied brick.

Fig. 10 illustrates may contain.

the mode of securing the tube-on its side by bolts l0, which face toward the manway in order that they may be readily removed in case a section should wear out or in case of its linal removal. It is intended that these ore-chutes shall be made of heavy sheets of plate-brass in order as far as possible to obviate the corrosive eects of the sulfate of copper. As these brass tubes wear out through the erosion of the ore that passes through them, the material is not lost or wasted. it passes, with the ore itself, into the smelter, and the copper thereof is thus recovered. In like manner, should a tube wear out from use it is removed, a new tube substituted for it, and the worn-out tube is thrown into the smelter or into the converter and its contained values thus in part recovered.

Fig. l1 shows my preferred mode of joining the sections of the tube. If a central section of the tube should wear out while in use, if the ore-chute were constructed with male and female joints one section could not be removed without involving the movement of and the emptying of ore from the entire chute. In order to prevent this inconvenience, l prefer to turn the end of each section around a me- IOS IIS

eoasae at tallic ring 11, as illustrated, and thereafter to bolt a strap or yoke 12, having' the form in cross-section of a segment o1 a circle, around the rings that constitute the ends of the two sections. The sections are thus bolted lirmly together, and at the same time any section of the chute may be readily removed by workmen in the manway simply by removing two t' the half-round clamps. Only so much of the orc in the chute as was above this one section need be drawn out through the gate below.

Variations will doubtless suggest themselves in the details ell the apparatus without departing from the spirit of my invention, since What l claim is-n 1. Aiiiparatus for mining` comprising a manway and a metallic ore-chute therein; substantially as described.
